Definitions

  • the invention relates to a method for fitting a breaking device tool with a bearing, a breaking device and a tool bushing used for a bearing.
  • the breaking device comprises at least a frame, a tool and a percussion device.
  • a percussion element in the percussion device By means of a percussion element in the percussion device, compression stress pulses are generated in the tool, which transmits them further to material to be broken.
  • a bearing bushing is arranged, a sliding surface on the inner periphery of the bearing bushing fitting the tool with a bearing to be movable in the axial direction of the tool.
  • a breaking hammer is a breaking device used as a supplementary device of an excavator or another basic machine when the intention is to break for instance rock, concrete or other relatively hard material.
  • the percussion device of the breaking hammer is used to give compression stress pulses to a tool attached to the breaking hammer, the tool transmitting the stress pulses to the material to be broken.
  • the tool is pressed against the material to be broken, whereby the effect of the stress waves and pressing causes the tool to penetrate into the material to be broken, which results in breaking of the material.
  • the tool of the breaking device is mounted on a bearing in the frame of the breaking device in such a way that it can move in the axial direction during the breaking.
  • the tool is usually mounted on a slide bearing by means of one or more bearing bushings.
  • the bearing bushing is attached to a tool bushing that is, in turn, attached to the frame of the breaking device.
  • the bearing bushing is a slide bearing that wears in use, due to which it has to be changed from time to time.
  • a problem with known solutions is that it is difficult and slow to change a worn bearing bushing in working site conditions.
  • US-6510904-B1 which discloses the features of the preambles of independent claims 1 and 6, discloses a hydraulic hammer including a polymeric tool bushing.
  • An object of this invention is to provide a novel and an improved method for fitting a breaking device tool with a bearing, a breaking device and a tool bushing.
  • the method according to the invention is characterized by locking the bearing bushing during the use of the breaking device in the axial direction to be substantially immovable in such a way that the tool is subjected to compression stress pulses, whereby the stress waves in the tool generate a movement perpendicular to the surface of the tool, which movement is transmitted to the bearing bushing, causing plastic deformation to the bearing bushing, and the bearing bushing to be locked in place in the bearing space.
  • the breaking device according to the invention is characterized in that the bearing bushing is locked in place in the bearing space during the use of the breaking device when the stress waves in the tool and the movement in the direction of the perpendicular of the tool surface due to the waves have caused the bearing bushing to be deformed permanently against the bearing space.
  • the tool bushing according to the invention is characterized in that the bearing bushing is arranged, during the use of the breaking device, to be deformed permanently and to lock immovably in the bearing space.
  • the breaking device tool is arranged through at least one bearing bushing, which fits the tool with a bearing in such a way that the tool can move in the axial direction relative to the frame of the breaking device.
  • the bearing bushing is an elongated piece made of slide bearing material and arranged in the bearing space. A clearance fit is arranged between the outer diameter of the bearing bushing and the bearing space to facilitate the mounting of the bearing bushing.
  • the bearing bushing is arranged to be subjected to stress waves of the compression stress pulses travelling in the tool, whereby the bearing bushing is arranged to be deformed by the effect of the stress waves.
  • the periphery of the bearing bushing is enlarged in the direction of the periphery and deformed.
  • the stress waves generated by a percussion device have two tasks: primarily they contribute to the breaking of the material to be treated, but they also cause the bearing bushing of the tool to be actually attached to its place in the bearing space.
  • An advantage of the invention is that the bearing bushing can be easily inserted in the axial direction to its place in the bearing space, since there is a clearance fit between the bearing space and the bearing bushing. No special pressing tools or the like are required for the mounting, but the bearing bushing can be inserted into the bearing space with manual force. Further, the bearing bushing is a simple utility item the manufacturing costs of which are small.
  • the idea of an embodiment of the invention is that the bearing bushing is prevented in the axial direction from getting out of the bearing space by means of one or more prelocking members.
  • the prelocking member keeps the bearing bushing temporarily in place until the bearing bushing is deformed and actually attached to the bearing space.
  • an embodiment of the invention is that at least one bearing space is positioned at the lower end of the breaking device on the side of the tool in such a way that the bearing space is open downwards in the axial direction.
  • the bearing bushing is insertable in the axial direction from below to its place in the bearing space without having to disassemble the lower frame of the breaking device.
  • An advantage of this embodiment is that it is quick and simple to change the bearing bushing. Further, since there is no need to disassemble structures of the breaking device, the changing may also take place in dirty working site conditions. As it is possible to change the bearing bushing in the working site, the interruption in the use of the breaking device can be as short as possible.
  • the breaking device comprises a tool bushing comprising a bushing frame the inner circle of which forms a bearing space for the bearing bushing.
  • the bushing frame may be immovably attached to the frame of the breaking device by means of one or more locking means.
  • the bearing bushing is arranged to be deformed during the operation of the breaking device in such a way that it is pressed against the inner periphery of the bushing frame in the radial direction.
  • the strength of the bushing frame is dimensioned to be greater than that of the bearing bushing so that substantially only the bearing bushing is deformed by the effect of stress waves.
  • the idea of an embodiment of the invention is that the bearing space is formed directly in the frame of the breaking device.
  • the bearing bushing is arranged to be deformed against the frame of the breaking device during the use of the device.
  • An advantage of this embodiment is that the breaking device does not need a separate bushing frame to form a bearing space.
  • the diameter of the hole to be made around the tool in the breaking device frame may be smaller than when a separate detachable bushing frame is used, which reduces the manufacturing costs.
  • the bearing space formed in the breaking device frame is particularly firm, whereby it can well receive the compression stress of the bearing bushing deformed during the use.
  • the bearing bushing is of bearing bronze.
  • Bearing bronze suits well to be used as the slide bearing of a breaking device tool, because it is deformed relatively easily due to the effect of stress waves, still having sufficient yield strength so that deformation causes compression stress in it, which keeps the bearing bushing in place in the bearing space due to the friction between the bearing bushing and the bearing space.
  • an advantage of bearing bronze is that it endures also short-term dry use without getting damaged when, for some reason or other, there is no lubricant film between the bearing bushing and the tool.
  • the wall thickness of the bearing bushing is between 8 and 12 mm.
  • the bearing bushing is sufficiently firm, so that sufficient compression stress is generated in it as a result of radial deformation. If the bearing bushing is not sufficiently firm, it does not stay properly in place in the bearing space. On the other hand, the wall thickness of the bearing bushing may not be so great that stress waves are not sufficient to generate deformation.
  • the idea of an embodiment of the invention is that the bearing bushing is prevented, by means of one or more prelocking member of light material, from getting out of the bearing space.
  • An advantage of a lightweight prelocking member is that it is not subjected to such great acceleration forces during the operation of the percussion device as would a piece manufactured of denser material.
  • the density of the prelocking member may be clearly smaller than that of the frame material.
  • the density of the prelocking member material may be below 3 000 kg/m 3 , whereas the density of the frame that is typically steel is about 8 0000 kg/m 3 .
  • the prelocking member may be manufactured of, for example, plastic material or reinforced plastic that has been reinforced with carbon, aramid or glass fibres or the like fibres.
  • the prelocking member may be manufactured of light metal, such as aluminium alloy. Furthermore, it may be manufactured of fibre material or even rubber. A prelocking member manufactured of light material does not, due to vibration, deform the locking surface made for it, such as a locking groove, locking opening or the like, because the acceleration forces directed at the prelocking member are relatively small. On the other hand, a prelocking member manufactured of less dense material is usually softer than a locking surface manufactured of denser material.
  • a prelocking member manufactured of less dense material than the locking surface may wear during the use due to vibration, but this has no significance because the purpose of the prelocking member is to keep the bearing bushing in the bearing space only until some stress compression pulses have been given to the tool by the percussion device and until the stress waves in the tool have deformed the bearing bushing in such a way that it is firmly pressed into the bearing space.
  • the prelocking member is a ring manufactured of plastic material, arranged in a groove on the periphery of the bearing space. It is simple and quick to arrange such a locking ring in place. Further, it is easy to manufacture inexpensive high-quality locking members of plastic material.
  • a breaking hammer 1 is arranged on a boom 3 in an excavator 2.
  • the breaking hammer 1 may be a hydraulic, pneumatic or electric device.
  • the breaking device 1 is pressed by means of the boom 3 against material 4 to be broken at the same time as compression stress pulses may be given to a tool 6 connected to the hammer with a percussion device 5 in the hammer, and the tool 6 transmits the stress pulses to the material to be broken.
  • the percussion device 5 usually comprises a reciprocating percussion piston striking a percussion surface at the upper end of the tool 6.
  • the percussion element may be an element other than a reciprocating percussion piston.
  • the breaking hammer 1 refers to the end on the side of the tool 6, while the upper part 1b of the breaking hammer refers to the end by which the breaking hammer 1 is attachable to the boom 3 or the like.
  • the breaking hammer 1 may be arranged in any movable basic machine or, for instance, on a boom attached to a fixed base, such as a rock crusher.
  • Figure 2 shows a very simplified operating principle of a breaking device.
  • a percussion element 7 of the percussion device 5 generates in the tool 6 compression stress (-), which propagates in the tool 6 as stress waves.
  • - compression stress
  • part of it may move on to the material 4 to be broken, and part may return as a reflected wave back towards the percussion device 5.
  • Travelling in the tool 6, the stress wave 6 generates a sudden small bulge 8 in the tool 6, in other words there is a sharp hammering movement 9 in the direction of the perpendicular of the tool surface in the tool 6.
  • the tool 6 is bearing-mounted on a frame 10 in the breaking device 1 by means of one or more bearings 11.
  • the bearing 11 is a slide bearing that is in contact with the tool 6.
  • the radial hammering movement in the tool 6 is transmitted from the surface of the tool 6 also to the bearing 11, this feature being utilized in the actual attaching process of the bearing 11 in the invention.
  • Figures 3 to 10 and the related description present embodiments and details of the bearing in greater detail.
  • Figure 3 shows a part of the lower part 1 a of the breaking hammer.
  • the percussion element 7 may be a movable percussion piston that strikes a percussion surface 12 at the upper end of the tool 6.
  • the tool 6 is arranged in the axial direction in the percussion element 7 and may be supported against the frame 10 by means of an upper bearing bushing 13 and a lower bearing bushing 14.
  • the breaking hammer 1 may comprise retainer means allowing a predetermined axial movement for the tool 6 but preventing the tool 6 from getting completely out of the breaking device 1.
  • Such retainer means may comprise one or more cross-direction retainer pins 15, for which a cross-direction opening is formed in the frame 10.
  • a thinned portion 16 may be formed in it at the point of the retainer pin 15.
  • the upper bearing bushing 13 may be arranged in the upper bearing space 17 from the direction of the percussion element 7 when the frame of the breaking device has been disassembled.
  • the upper bearing bushing 13 may be supported in the axial direction with a shoulder 18 and a counter-ring 19 or the like.
  • the upper bearing bushing 13 may be manufactured of slide bearing metal, and it may contain lubricant channels along which lubricant may be conveyed to its slide surfaces.
  • the lower part of the frame 10 is provided with a space 20 open towards the outer surface of the frame 10, in which space 20 a tool bushing 21 is arranged from below, in the mounting direction A, the tool bushing 21 comprising a bushing frame 22 and a lower bearing bushing 14 arranged inside it.
  • the tool bushing 21 is supported by its upper end against a shoulder 23 in the frame 10 and locked with one or more locking means, such as a cross-direction locking pin 24a and locking grooves 24b and 24c in such a way that it cannot get out of the space 20.
  • the inner periphery of the bushing frame 22 forms a bearing space 25, into which the bearing bushing 14 is inserted.
  • the end of the bushing frame 22 on the side of the percussion element may comprise a shoulder 26, against which the bearing bushing 14 may be inserted.
  • the movement of the bearing bushing 14 in the axial direction may be prevented in such a way that the shoulder 23 in the frame 10 extends to the portion of the bearing bushing 14 as well.
  • the purpose of the prelocking member 28 is to prevent the bearing bushing 14 from getting out of the bearing space 25 after the mounting and before the bearing bushing 14 has been attached to the bearing space 25 as a result of the deformation.
  • the prelocking member 28 may be a cross-direction pin or another member suitable for the purpose.
  • the lower bearing bushing 14 When the lower bearing bushing 14 has worn out, it may be replaced through the lower part of the breaking hammer without having to disassemble the lower part of the frame 10, or without even having to detach the tool bushing 21.
  • the bearing bushing 14 may be provided with one or more lubricant channels 29, along which lubricant may be conveyed to its slide surfaces.
  • the bushing frame 22 may comprise channels 30, as may the frame 10, for conveying lubricant to the bearing bushing 14.
  • Figure 4 shows the assembled tool bushing 21.
  • Figure 5 shows the bushing frame 22 and the diameter D1 of the bearing space 25.
  • Figure 6 shows the bearing bushing 14 and its outer diameter D2.
  • the diameter D1 has been dimensioned greater than the diameter D2, in other words there is a small clearance between the bearing bushing 14 and the bearing space 25.
  • the components arranged within each other have thus a clearance fit.
  • the distance between the shoulder 26 and the groove 27 in the bushing frame 22, i.e. the length L1 of the bearing space 25 is greater than or equal to the length L2 of the bearing bushing 14 in order for the bearing bushing 14 to be arrangeable inside the bushing frame 22.
  • Figure 6 further shows the outer periphery 31 of the bearing bushing 14, serving as the attachment surface against the bearing space 25, and the inner periphery 32 of the bearing bushing 14, serving as the slide surface against the tool 6.
  • Figure 6 indicates the wall thickness W of the bearing bushing 14, which may be between 8 to 12 mm.
  • the bearing bushing 14 is sufficiently firm so that required compression stress can be generated in it as a result of radial deformation. If the bearing bushing 14 is not sufficiently firm, it does not stay properly in place in the bearing space 25. On the other hand, the wall thickness W of the bearing bushing 14 may not be so great that the stress waves 9 are not capable to generate radial deformation in the bearing bushing.
  • Figure 6 indicates the inner diameter D3 of the bearing bushing 14, dimensioned greater than the outer diameter of the tool 6 in order for the slide bearing to function in general.
  • Figure 7 shows an alternative structure of the lower part 1 a of the breaking hammer, in which, deviating from Figure 3 , there is no bushing frame 22 but the lower bearing bushing 14 is arranged in the bearing space 25 formed in the lower part of the frame 10.
  • the lower part of the bearing space 25 may extend as far as to the outer surface of the lower part of the frame 10, whereby the bearing bushing 14 may be pushed in the mounting direction A from below to its place in the bearing space 25 without having to disassemble the frame 10.

By its lower end, the bearing bushing 14 may be supported with a suitable prelocking member 28 at least until it has been deformed in the radial direction against the bearing space 25 and locked in place.
  • Figures 8 and 9 illustrate how the bearing bushing 14 is attached to the bearing space 25.
  • the stress waves 9 travelling in the tool 6 generate on the tool surface a movement in the direction of its perpendicular, the movement being transmitted to the bearing bushing 14. This small hammering movement is illustrated with arrows in Figure 8 .
  • After the mounting there is a small clearance 33 between the bearing bushing 14 and the bearing space 25.
  • the hammering movement due to the stress waves shapes the bearing bushing 14 and causes the bearing bushing 14 to expand, whereby its outer periphery is pressed against the bearing space 25, and the clearance 33 disappears.
  • the bearing space 25 may be of steel or corresponding material that is stronger than the bearing material and is capable of receiving the compression stress caused by the expansion of the bearing bushing 14 without the bearing space 25 being essentially deformed.
  • the bearing bushing 14 may be manufactured of suitable bearing metal, such as bearing bronze. Alternatively, the bearing bushing 14 may be manufactured of any deformable slide bearing material, even plastic material or the like.
  • Figure 10 illustrates two alternative ways to remove the bearing bushing 14 deformed by the stress waves 9 from the bearing space 25.
  • the tool 6 is detached, and the prelocking member 28 is removed if it is still there after the use.
  • one or more longitudinal welding beads 34 may be welded on the inner periphery of the bearing bushing 14, which causes the bearing bushing 14 to contract in such a way that it can be drawn out of the bearing space 25.

  • the bearing bushing 14 can be removed with conventional tools in working site conditions.
  • the upper bearing bushing 13 is attached to its place in the upper bearing space 17 by using stress waves 9 travelling in the tool 6, which stress waves deform the bearing bushing 13 in the radial direction and cause it to be pressed firmly against the bearing space 17.
  • the upper bearing bushing 13 may be supported against the bearing space 17 with one or more prelocking members 28, due to which it is not necessary to support it in the way shown in Figure 3 by means of a shoulder 18 and a counter-ring 19.
